Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

Referring to fig. 1, a connector is shown schematically, and a zero insertion force (Zero Insert Force, ZIF) connector is used as a common flexible circuit board (Flexible Printed Circuit board, FPC) connector, and can be applied to various fields of digital communication products, portable electronic products, measuring instruments, automotive electronics, and the like, such as mobile phones, digital cameras, notebook computers, handheld game consoles, audio equipment, and the like.

The ZIF connector has a structure as shown in fig. 1, and includes a metal terminal a for transmitting signals, a plastic chamber b for fixing a connection terminal in a flexible circuit board (FPC) d, and a locking cover c for fixing the FPC, which may include a piano cover (insulator). ZIF connectors are typically assembled laterally and can be assembled automatically. Because of their special assembly, ZIF connectors have found wide application in applications such as the connection of LCD displays to related devices (e.g., controllers or driver circuits) in printed circuit boards (Printed Circuit Board, PCBs).

Under normal conditions, after the ZIF connector is assembled with the FPC, due to the design of the FPC, redundancy with a certain length exists in the length direction, and in addition, the FPC is pulled in the assembly process and stress exists on the FPC after the assembly, the lock cover can be pushed open by the FPC, so that the locking failure of the lock cover is caused. The FPC may come off from the ZIF connector to be separated from the ZIF connector, eventually resulting in disconnection of electrical connection between the FPC and the ZIF connector.

Referring to fig. 2, a schematic diagram of a fixing scheme is shown, after the FPC is fixed on the ZIF connector, foam is added at a corresponding position on the housing of the electronic device or a first film (Mylar) e with a fixing effect is added on the ZIF connector, and the area of the fixing film is substantially equal to the occupation area of the ZIF connector, so as to prevent the lock cover from being automatically opened. Referring to fig. 3, another fixing scheme is shown in fig. 2, and a second film (Mylar) f with fixing function is attached to fix the ZIF connector, the lock cover c and the FPC, wherein the size of the second film can be determined according to actual requirements. Other areas except for the areas covering the ZIF connector and the FPC in the second film are adhered to the PFC, and the ZIF connector g, the lock cover c and the FPC are fixed on the PCB.

In practical use, because of the small size of the ZIF connector itself, it is difficult to cover the surface of the ZIF connector with a film (Mylar) for fixing the piano cover, as shown in fig. 2. A large area of film is typically applied to secure both the ZIF connector and the FPC in the manner shown in fig. 3. Because the difference in height that exists between ZIF connector and the PCB board, there is redundancy in length in addition to FPC, and the film can not laminate completely, is relatively poor to the fastness of fixing of piano lid and FPC on the ZIF connector.

Referring to fig. 4, which is a schematic cross-sectional view of a connector, referring to fig. 5, which is another schematic view of the connector shown in fig. 4, and referring to fig. 4 and 5, the connector includes:

The metal reinforcement piece is assembled in a PIN inserting mode, two barb features are needed to be included, interference and fixing are formed between the metal reinforcement piece and the plastic cavity, and assembly reliability is guaranteed. One side of the metal reinforcing piece is provided with a material strip cutting position, so that the assembled material strip is convenient to cut, and the assembled material strip is cut according to the structure of the connector body and the PCB to form a locking terminal with matched appearance. The cutting position of the material belt can be determined according to actual requirements.

According to the embodiment of the disclosure, the locking terminal is added on the ZIF connector body, so that after the ZIF-FPC is assembled and the piano cover is buckled, the lock hook of the locking terminal is inserted into the lock hole of the FPC, locking of the FPC is achieved, compared with a scheme of sticking the Mylar, the locking terminal is more convenient and rapid, a station specially sticking the Mylar can be omitted, assembly is more efficient, and automation can be achieved.

Compared with the scheme of pasting film Mylar, through the latch hook of locking terminal and the hasp cooperation on the FPC in order to realize the locking to FPC, this kind of scheme is obviously more reliable, can realize more reliable fixed to FPC, and this kind of locking structure can effectively avoid FPC to take off under the exogenic action, obviously improves the reliability of electric connection between ZIF-FPC.

The ZIF connector assembly with the locking terminal is assembled in place and then buckled with the piano cover in the actual use process, and a film Mylar is not required to be attached for fixing the FPC. The thickness of the film Mylar is generally about 0.05mm, and compared with the traditional film Mylar pasting, the ZIF connector capable of realizing locking can save the Z-direction space of 0.1mm for the whole machine by saving two layers of films Mylar.

Compared with the traditional ZIF connector fixing mode, the embodiment of the disclosure has the advantages that the structure and the PCB department cloth can be facilitated without considering the clearance of the Mylar positions of the adhesive films, the stacking is superior, and the cost is also superior because of the two saved Mylar films.

This patent has solved ZIF connector after with FPC equipment, because pile up the design, FPC generally can have the bending of certain direction, and in addition the stress that exists after the equipment and the pulling to FPC in the equipment process, in the daily use of product, FCP pine takes off and leads to the problem of electrical connection inefficacy.

Compared with the scheme of sticking the film Mylar, the ZIF connector assembly with the locking terminal is more convenient, a work station special for sticking the film Mylar can be omitted, assembly is more efficient, and automation can be achieved.

The structure for locking the specific terminal and the lock hole on the FPC is difficult to pull out the FPC by bending stress or pulling of external force of the FPC, and in addition, the pull-out force of the FPC can be improved, so that the ZIF-FPC is more reliable in electric connection.

According to the ZIF connector with the locking terminal, mylar is not required to be attached after assembly is completed, the Mylar thickness is generally about 0.05mm, and compared with the traditional Mylar attaching ZIF connector, the ZIF connector with the locking terminal can achieve locking, and the saved two Mylar layers can save 0.1mm Z-direction space for the whole machine.

The ZIF connector with the locking terminal provided by the embodiment of the disclosure further comprises two metal reinforcing pieces, so that the lateral strength of a ZIF connector product can be effectively enhanced, damage of the product caused by improper assembly is prevented, and the damage rate of devices is reduced.

After the scheme is assembled, a film Mylar is not required to be pasted, cloth pieces can be allowed to be arranged on the periphery of the device, and advantages exist on stacking.

The film Mylar is not required to be adhered after the scheme is assembled, so that the cost can be reduced from the aspects of materials and assembly, and the method has more advantages in the process of model selection.
